Arccotangent function
See Inverse cotangent function.

Binomial theorem
A theorem that gives an expansion formula for (a + b)n

Coefficient of determination
The number r2 or R2 that measures how well a regression curve fits the data

Coordinate(s) of a point
The number associated with a point on a number line, or the ordered pair associated with a point in the Cartesian coordinate plane, or the ordered triple associated with a point in the Cartesian threedimensional space

Data
Facts collected for statistical purposes (singular form is datum)

Direction vector for a line
A vector in the direction of a line in threedimensional space

Geometric sequence
A sequence {an}in which an = an1.r for every positive integer n ? 2. The nonzero number r is called the common ratio.

Imaginary part of a complex number
See Complex number.

Independent variable
Variable representing the domain value of a function (usually x).

Limit
limx:aƒ1x2 = L means that ƒ(x) gets arbitrarily close to L as x gets arbitrarily close (but not equal) to a

Linear equation in x
An equation that can be written in the form ax + b = 0, where a and b are real numbers and a Z 0

Linear function
A function that can be written in the form ƒ(x) = mx + b, where and b are real numbers

Magnitude of a vector
The magnitude of <a, b> is 2a2 + b2. The magnitude of <a, b, c> is 2a2 + b2 + c2

Mathematical induction
A process for proving that a statement is true for all natural numbers n by showing that it is true for n = 1 (the anchor) and that, if it is true for n = k, then it must be true for n = k + 1 (the inductive step)

Quartic function
A degree 4 polynomial function.

Sinusoidal regression
A procedure for fitting a curve y = a sin (bx + c) + d to a set of data

Speed
The magnitude of the velocity vector, given by distance/time.

Statistic
A number that measures a quantitative variable for a sample from a population.

Tangent line of ƒ at x = a
The line through (a, ƒ(a)) with slope ƒ'(a) provided ƒ'(a) exists.

Upper bound for real zeros
A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.
